DUMP WAGON.

Application led November 19, 1925. Serial No. 70,121.

This invention relates to an improvement in a dumping Wagon, and more particularly to a Wagon in which the body is pivotally mounted, so that it may assume three positions, acting in one position as a scraper to take on material, in another position to dump the material and in the third or intermediate position to carry the material from one point to another.

The rimary. object of this invention is to provlde a dumping wagon of this type in which the body is normally in the carrying position, but can be shifted to either the scraping position or dumping position l5 easily, being caused to assumesuch positions by the operation of a shaft actuated either manually or by the forward traction of the rear wheels.

.Other objects of this invention will ap- V'0 pear from a consideration of the following description taken in connection with the drawin s, which form apart thereof, and in whic Fig. 1 is a plan view of a wagon embodying this invention with thebody in the carrying position;

Fig. 2 1s a perspective view showing the body in the scraping position;

Fig. 10 is a sectlonal view along the line 10-10 of Fig. 1; and

Fig. 11 is a viewshowin another form of axle that might be used i desired.

This invention isl shown as embodied in a four wheel wagon 10, but it is understood that it could equally well be embodied in a wagon having only a single front wheel or in a trailer having no front Wheels at all, the essential point being the mounting of the wa on body 11 on the frame so it can be shi ted from the scraping sition into the carrying position or from t e carrying posi-` tion into the dumping position by the rotatlon of the supporting or rear wheels. The wagon frame comprises the side rails 12 and the cross rails 13, which may be of channel iron, as shown in the drawing.

The rear axle 14 is preferably rigidl secured tothe body 11, as shown partie arly in Fig. 5 and is pivotally supported by the side rails 12. .The wheels 15 are mounted in any suitable manner to rotate freely upon the ends of the axle 14, so that under ordinary conditions the traction of the wagon will have no effect whatsoever upon the axle' 14 or the position of thebody 11. Rigidly secured to the hub 16 of each wheel 15 is a sprocket 17 and mounted u on each side rail 12 is a stub shaft 18, w 'ch carries a sprocket 19 in alinement with the sprocket 17. A chain or other connecting means 20 1s employed to transmit motion between the sprockets 17 and 19, as shown in the drawings particularly in Fig. 4. It will be noted that the sprocket 17 is much larger in diameter than the sprocket 19 for obviousv reasons.

Rigidli secured to the sprocket 19 and carried by t e stub shaft 18 is a gear 21, which meshes with a gear 22 mounted to rotate freely on a cross shaft 23. A clutch connection of the gears 22 withthe shaft 23 is provided so that the gears can either rotate said shaft or can rotate freely thereon. For

urpose of illustration the drawings show one type of clutch connection. The hub 24 of the ear 22 is provided with a notch 25, adapte to receive a boss 26 on the shaft 23. A coil spring 27 on the shaft 23 between the gear 22 and a locking nut 28 normally acts to urge the gear 22 laterally inward so that the boss 26 will enter the notch 25 in the hub 24, and any rotation of the wheels be transmitted to the shaft 23.

In order to counteract this spring tendency and to prevent this inward movement of the gear 22 and keep the boss 26 out of the notch a suitable shifter mechanism may be employed. This may consist of a plate 29 pivotally mounted at 30 on a side, rail 12, and havmg three arms 31, 32, and 33. The arms 32 and 33 extend in o posite directions from the pivot 30, while t e arm 31 `projects at right angles from the arm 32. The arm 31, when the plate is shifted on the lpivotal connection 30, will bear against the inner face of the gear 22 and force it laterally against the action of the spring 27, moving the notch awaytrom the boss 26. Secured to the arm 33 of the plate 29 is a rod 34 which extends to the iront of the vehicle and is attached to a lever 35, rigidly secured to a cross rod 36 mounted to rotate in the side rails. By raising the lever 35 the plate 29 is shifted on the pivot 30 pressing the arm 31 against the gear 22. rlihis operation will be obvious from a consideration of Figs. 1 and 2 ot the drawing.

@nly the set of gears on one side have been described, but it will be understood that the other set functions in the same manner, and the same reference characters have been applied to each in the drawing. The plan view in Fig. 1 illustrates this mechanism, but it will be noted that only one shifter plate 29 with its associated elements is shown. rlhis is because that to show the omitted plate would interfere with the showing of the brake mechanism described hereinbelow. rlhe form ot the notches 25 is such that unless the bosses 26 are fully seated therein, the gears will tend to move laterally and automatically declutch themselves.

'lhe cross rod 36 is provided at the end opposite the lever with a Xed plate 37, to which a rod 38 similar to the rod 34 is attached. rllhe rod 38 transmits the movenient oi the rod 36 to the other shifter plate 29, (see Fig. 3)` so that both gears 22 will be thrown out simultaneously.

As a regulator or check upon the movement ot the shaft 23 a brake 40 is provided. Ylhis brake comprises a strap 41, which passes over a drum 42 integral with the shaft 23 near one of the side rails 12. @ne end ot thestrap 41 is secured to the rear cross rail 13 and the other end is secured to one arm 43 o1 a right angle lever 44, pivoted to the inner lace o1 the side'rail 12. The other armv 45 of the lever extends below the side rail 12 and terminates in a llange 46, which passes across and below the rail 12.

Supported by and above the doorlooard 47 on the trarne is a bar 48, which terminates at one end in a pedal 49, and is pivcted at 50. A simil" bar 51A is sup-ported by and below the 'lloor board 47 being pivoted there to at 52. The end ,ol the bar 48 oppositethe pedal 49 is connected to one end ot the bar 51 by a linlr 53. vlo the other end ont the bar 51 is attached a rod 54 which connects the bar 51 to the flange 46 of the lever 44. By applying pressure upon the pedal 49 the strap 39 is tightened upon the drum 42 ol the shalt 23 and regulates its movement.

The wagon body 11 consists oi? a nia-in portion or box 60, which is rigidly fixed to the rear axle 14. rl`he boi; is made in the torni ot a scoop having a bottom 61, side walls 62 and upper rear wall 63. lin place of a hired front wall there is provided a iront gate 64 having side flanges 65, which tomate are pivoted upon the side walls 62 of the boX 60 at 66 and 67. Fixed at the inner corners of the side and rear walls are angle .iron posts 68, which project above the walls and have holes 69 therein for a purpose to be described hereinbelow.

At the inner corners of the gate 64 are fixed angle iron posts 70 similar to the posts 68, and also provided with holes 71 therein. l-lorizontal bars 72 are iiXed tothe iront face of the gate 64, the ends of the bars extending outwardly beyond the flanges 65. Notched supports 73 are secured to the side rails 12 in such a position that when the body is in the carrying position with the .front gate 64 closed, (see Fig. 4), the bars 72 rest upon the notches 74 in tle supports 73 and hold the body in that position. liue to its weight and the location of the pivots 66 and 67 the gate 64 normally tends to close the iront or" the box 60.

Mounted to slide in straps 75 on the front ot the gate 64 is a late 76, (see Fig. 6).. rl`he lower end of the p ate 76 passes through the space between the gate 64 and the floorboard 47 and has an outwardly projecting llange ,77, which extends across the space below the board and to the upper end is pivoted at 78, one end of a lever 79.v rlFhe lever 79 1s pivoted at 8O to the gate 64 and has a handle 31, which projects above the gate 64. Fixed to the llange 77 is a chain 82, which rests on the idoorboard 47 and which is 'used to raise the plate 76 when desired, as will be set i'orth later.

When the plate 76 is lowered from the ico Fig. 6 position vthe dange 77 will strike the oorboard, should the gate swing on its pivot, so that when the plate is lowered, the gate can not be opened. n

The box 60 also has a rear gate 83 which normally closes the space between the upper rear wail 63 and the back edge of the bottom 61. The gate 83 has right angle danges 84 pivoted at 85 to the side walls 62. Rigidly secured to the upper edge of the gate 83 is a bar 85, the ends of which project be yond the sides of the gate for a purpose to be described below.

Adjust-ably tixed in pockets 86 on the side walls 62 by screws 87 are angle brackets 38, which can be adjusted so that the upper arms 89 are at any desired distance above the pockets 86. The under face ot' the bottom 61, of the box 6C, at the front edge is reinforced by a metal plate 90, the front edge 91 of *vhich is preferably sharpened, as shown in lhe posts 68 are higher than the posts 70 and have two set-s of holes 69 therein. The shalt 23 is supported in brackets 92 and has an enlarged portion or drum 93 between the brackets 92. Rigidly secured to the center of the drum 93 and to the upper holes 69 in the bars 68 is a line or cable 94.l

` iso The gears 22 are under ordinary conditions declutched from the shaft 23, the lever being held in that position by means of ai chain 95 which is secured to the handle of the lever, and one of the bars 70, (see Fig. 4.)

Furthermore, by reason of the iat face 96 of the arm 3l, the pressure of the gear when declutched will bear across theentire face of the arm 31, and consequently will exert no tendency to swing the plate 29 on its pivot 30. When so set the wagon is used in the usual manner, the body being in the carrying position shown in Fig. 4. Upon reachp ing the place where the wagon is to pick up material the chain 82 is pulled up, rst raising the plate 76 and drawing the flange 77,

through the space between the floorboard and the front gate and then swinging the gate 64 on its pivots 66, 67, until the bars 72 leave the notches 74 in the supports 73. This removes the support for the front end of the box 60, which swings downwardly about the axle 14 while the gate slides down on the floorboard 47 under the support 96 for the seat 97. The box will swing down until the arms 89 of the brackets 88 strike the side rails 12 or the blade 79 rests on the ground.

The gears 22 being declutched, the wagon is drawn forward to scoop'up the material until the body is filled. The lever 35 is then depressed to swing the plate 29 and permit the gears 22 to clutch the axle 23. so that as the wagon goes forward the shaft 23 and its drum 93 are rotated, winding up vthe cable 94 on the drum and raising thebody from the scraping position. As the body ,is raised the front gate 64 will swing back into its normal position, which will be reached when t-he body has been raised, sulil ciently, so that the bars 72 are above the notches 74 in the supports 73.. If the chain 95 is not attached to the posts 70 the gears 22 are thrown out by raising the lever 35 and the body takes its normal carrying position.

When the body is in the scraping position the posts are so located that the chain 95 can be secured in one of the holes 71, when the lever 35 is`depressed. As the body rises the posts 70 also straighten up and when the front gate is closed the posts 70 have reached such a position that the lever 35 is raised and the clutch thrown out automatically when the wagon is in the carrying position.

When the unloading point has been reached the gears 22 are again thrown into clutch with the axle 23 by removing the chain 95 from the post 70 and depressing the lever 35, so that, as the wagon oes forward the cable 94 is wound on the rum 93 tilting the body backward on the axle 14. The cross barv 85 on the rear gate 83 strikes the side rails 12, so that the gate o ens as the body is tilted and the load sli es out. As the body continues to tilt back the cross bar 85 slides along the rails until it strikes the .takes place the axle 23, of course. is free to turn and the cable 94 to unwind from the drum to lower the, body, but this may be prevented by the use of the brake 40, which can be set by the pedal 49 to hold the drum 93 stationary. When the load has been dumped the brake 40 is released allowing the body to return to its normal carrying position and the operations described are reeated.

Should there be an necessity for shifting the position of the ody when the wagonl is stationary the ends 98 of the shaft 23 are made rectangular and a lever 99 having a rectangular hole therethrough is provi ed so that the axle 23 can be turned manually in the proper direction.

, The wagon here illustrated is of the four wheel type intended to be drawn by a pir of horses. The licor-board 47 is braced the front cross piece 13 by channel irons to whichare secured the front axle 100 and the shafts 101. Since as pointed out above this forms no part of applicants invention and is shown for purposes of illustration only, it will not be described in detail.

While certain embodiments of this invention have been shown and described, applicant is not limited thereto, since it is obvious that other embodiments can be made without departing from the spirit and scope of this invention as set forth in the following claims.
